GSM-based Automatic Voltage Protection System for Residential Small Appliances

A voltage protection system is one of the essential things in most of residential and home appliances. It is a low-cost, easy-to-use system that safeguards electrical and electronic devices and low-power home appliances. The main goal of this research is to create a system that can detect undervoltage and overvoltage conditions and regulate the associated output of different loads. The proposed protection system is developed and analyzed in the Proteus flatform. A voltage divider circuit and a voltage regulator are attached to the Arduino Pro Mini in the protection model, which determines whether the voltage level is accurate. When the GSM module is turned on, the user receives a message that says “System Initializing”. When the voltage reaches a threshold level, it notifies the user that “System is ON”. Otherwise, it notifies the user that “System is OFF”. Several case studies reveal that the system protects small residential and home appliances from undervoltage and overvoltage.
